Re: Breakfree Bore Cleaning Foam
hydro, it is a one step process, cover everything you want to clean the fouling off with the foam, let it sit for around 1/2 hour (longer doesn't hurt but doesn't accomplish a thing)
run dry patches through the bore till they come out clean,(4-7) wipe everything else and you are done. The foam turn into a oily like liquid, blue means the copper is coming off, I ran over a 1000rds of corrosive surplus 5.45x39 through an Ak74 full-auto in one afternoon, that gun was disgusting, the foam took care of everything, it came out dark purple!!! after the treatment the AK was nice and clean.
hope this helps.
